Air energy heat pump is a heat pump that uses the inverse Carnot principle to absorb heat from the air to create hot water. Handling device. By allowing the working medium to continuously complete the thermodynamic cycle process of evaporation (absorbing heat from the environment), compression, condensation (releasing heat), throttling, and re-evaporation, the heat in the environment is transferred to the water. An important parameter to evaluate the performance of a heat pump is the heating capacity. The heating capacity of a heat pump is affected by three major factors.
, the operation mode of the hot water system
When the system mode of constant temperature water replenishment and circulating heating is used to heat hot water, the heat pump unit in the system is always working at medium to high water temperature, resulting in the actual performance coefficient of the heat pump being less than The theoretical coefficient of performance of a direct heating system that heats cold water to hot water drops by more than %. It is precisely the lack of direct heating control technology that affects the actual energy-saving effect of many heat pump hot water projects
, circulating water flow and scale
"Heat Pump Water Heaters for Commercial or Industrial and Similar Purposes" clearly states : For hot water machine laboratories that do not provide water pumps, choose a water pump so that the temperature of the heat exchange end of the circulating water rises by degrees Celsius under the nominal heating capacity of the unit. From the perspective of most circulating commercial machines currently on the market, due to the fact that the pipelines in actual engineering design The resistance loss varies in size. In some engineering systems, the circulating water flow is small and the heat exchange end temperature rise exceeds the heat transfer decrease, so the heating capacity of the unit will also decrease. Scale in pipes and heat exchangers will affect water flow, increase the thermal resistance of the heat exchanger, and reduce the heating capacity of the unit. Therefore, after a certain number of years of operation, the heating capacity of the heat pump unit will decrease. The heating capacity will also decrease in places with poor water quality
. Influence of climate conditions
When the ambient temperature of the heat pump unit reaches ℃, then Its heating capacity can be increased by more than %%. Especially in winter, the heating capacity is greatly affected by the temperature. When designing a plan, the heating capacity and performance system under experimental conditions are often used as the annual average value of the heat pump unit and compared with electric water heaters and gas water heaters to get the conclusion that excellent energy-saving effects are achieved. However, this data is far from reality. The large deviation is because the influence of climatic conditions in different regions is not considered. For example, in the area north of the Yangtze River Basin, the deviation between the annual average energy efficiency of heat pumps and the nominal operating condition energy efficiency may exceed %.
